+Subject: [PATCH 1/1] configure.ac: add option to disable image output
+
+Even when the gd library is present, it may be desirable to not build
+'vnstati' as image output is an optional feature.
+
+Also, when testing for the gd library, use gdImagePng() instead of
+gdImageLine() since it's possible that the installed gd library doesn't
+have PNG support. In such cases, the test in the configure script passed
+(because gdImageLine() is always present), but the build failed with:
+
+  src/vnstati.o: In function `writeoutput':
+  vnstati.c:(.text+0x3fc): undefined reference to `gdImagePng'
+  collect2: error: ld returned 1 exit status
+
+Upstream status: accepted, not yet released.
